Although the tombs have been excavated, a large number of precious cultural relics have been unearthed. Ding, pot and many other bronzes are engraved with long inscriptions, which record the history that Sun Yat-sen took advantage of the meditation of the Prince of Yan to cause civil strife, sent troops to cut Yan and achieved brilliant results. The inscription also reflects the politics and culture of Zhongshan in many ways. Large herringbone bronze ware is a very distinctive ritual vessel in Zhongshan State. The dragon and phoenix bronzes, gold and silver animal-shaped screen seats, bronze cymbals and ancient wines unearthed in the tomb are extremely rare treasures. The "Zhaotu" copper plate unearthed indoors is valuable information for studying the layout and shape of tombs in the Warring States period. The copper plate is 94 cm long, 48 cm wide and about 1 cm thick. The plan of Sun Yat-sen Mausoleum is embedded with gold and silver, and the dimensions of each part of the cemetery are marked in detail.
